Abstract
The invention provides a metal die preheating device. A first split-flow branch pipe and a second split-flow branch pipe are respectively arranged at two ends of a heating main pipe, and an initial end of the heating main pipe is provided with a tee connector which is respectively provided with a first connector through a first valve and a second connector through a second valve. The metal die preheating technology of the metal die preheating device includes the steps of firstly opening dies at two sides of a metal die, then fixing the metal die preheating device on the metal die so that the first split-flow branch pipe is floated in a shape cavity of the metal die and the second split-flow branch pipe is floated in a pouring gate of the metal die, then connecting a fuel source on the first connector and connecting a pneumatic supply on the second connector, opening valve switches so that fuel gas flows into the two split-flow branch pipes through the heating main pipe to be ignited and burned after flowing out of nozzles, and adjusting size of flame by adjusting switches of two valves until the metal die is evenly heated to reach relevant technology parameters. The metal die preheating device and the metal die preheating technology of the metal die preheating device has the advantages of being capable of solving the problems that the existing die is low in service life, long in heating time, high in cost, large in labor intensity of workers and unstable in the technology parameters.
Description
Technical field
The present invention relates to preheating device for metal mould and pre-heating technique thereof that aluminium parts gravity casting and low-pressure casting casting technique are used, be specifically related to preheating device for metal mould and metal die pre-heating technique thereof.
Background technology
At present, all at gravity casting and low-pressure casting explained hereafter alloy product (aluminium parts) before, all need metal die is carried out preheating, each mold heated evenly and after being heated to 300 ± 50 ℃ (technological requirement of different product is different) is just begun to pour into a mould product., out-of-shape many due to the metal die quantity of some product, size is larger, position distribution is irregular features such as (particularly cups), and be subjected to the impact of these factors, existing pre-heating technique adopts two firelocks to carry out the flame burning facing to mold cavity mostly, that this technique can cause burning is inhomogeneous, the temperature local temperature difference is large, thereby causes be heated inequality, life-span of mould to reduce; Make temperature all reach relevant requirements, will make local temperature too high, waste combustion gas, lose time, increase cost; If only have local temperature to reach requirement, former products of output are wasted as scalding module (being waste product), increase material, artificial, combustion gas cost.And cup and mold cavity generally can not heat simultaneously due to position problems, thereby the sequencing that produces causes lengthen preheating time, the problems such as waste of fuel.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of metal die be heated evenly, local temperature difference is less, technique is simple, operation is practical and convenient preheating device for metal mould and metal die pre-heating technique thereof.
Purpose of the present invention is realized by following technical scheme: preheating device for metal mould, comprise the heating supervisor, be equipped with under the first shunt pipe, its other end under described heating supervisor's a end the second shunt pipe is housed, initiating terminal described heating supervisor is equipped with three-way connection, an end of this three-way connection by the first valve the first joint is housed, its other end is equipped with the second joint by the second valve.
According to the metal die pre-heating technique of described preheating device for metal mould gained be: at first, metal die is loaded onto board, its two side form is opened to both sides respectively, then this preheating device for metal mould is fixed on metal die, allow its first shunt pipe be suspended in the middle of the die cavity of metal die, the die cavity position of main heating of metal mould allows its second shunt pipe be suspended in the middle of the running channel of metal die, the running channel position of main heating of metal mould; Again gas hose and the air hose of fuels sources, pneumatic supply are received respectively on the first joint, the second joint, and open the switch of first, second valve, under the condition of air pressure, combustion gas is responsible for by heating, flow to two shunt pipes, combustion gas is evenly flowed out from the nozzle of the first shunt pipe, the second shunt pipe, and then ignition on this nozzle, the size of regulating at last flame by the switch of regulating two valves; After the metal die homogeneous heating reaches the related process parameter, then with two valve switch Close Alls.
After adopting the present invention, die cavity and running channel two parts to metal die heat simultaneously, make that metal die is heated evenly, local temperature difference is less, utilize simple to operate and highly versatile and the low characteristics of cost, only need this preheating device is put into metal die, connect gas hose and air hose, then igniting, process time in accordance with regulations closes, and just can solve current die life low, and heat time heating time is long, cost is higher, labor strength is large, the unsettled problem of technological parameter.And this preheating device structure, technique are simple, make easily, and cost is lower.
According to design concept of the present invention, special characteristics according to each metal die, appropriate change and increase its internal shunt arm and nozzle thereof, make any one position that the flame of ejection can the homogeneous heating metal die, thereby the temperature one-time heating that realizes metal die is to needed technological parameter.
